PORTABLE HEATER Specification of Letters Patent.

Patented Dec. 5, 1905.

Application filed April 27, 1905- Serial No. 257,638-

To all whom zltma'y concern.-

,Beit known that I, CHARLES T. CLARK, acitizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Portable Heaters; and I do hereby declare that the following is a full, clear, and

exact description of the same, reference be- "struction hereinafter described, and particularly pointed out in the claim.

Similar numerals of reference indicate correspondingparts in both the figures of the drawings.

. In the accompanying drawings, 1 represents a radiator of any general design and construction commonly used in hot-water heat ing systems and is preferably mounted upon the platform 2, which platform is mounted upon casters 3 for the purpose of convenience in moving the heater proper from place to place, as desired, or connecting the heater in diiferent rooms or places where gas-pipes, such as 4, may be located, by which arrangement a portable water-heater is produced. Near the bottom or lower end of the radiator 1 is located the water-pipe 5, which waterpipe is connected to the T 6, from which T extends the coiled heatingepipe 7, which coiled heating-pipe is located directly above the burner Sand within the casing 9, which casing is formed of a length to correspond with the length of the coiled heating-pipe 7 For the purpose of utilizing substantially the entire amount of heat produced by the burner 8 the convolutions of the coiled heating-pipe are formed of a diameter corresponding substantially with the diameter of the casing 9, as illustrated in the drawings. From the coiled heating-pipe 7 extends the pipe 10, which pipe is connected to the elbow 11, and to the elbow 11 is connected the pipe 12, which pipe communicates with thetop or upper end of the radiator 1, as illustrated in Fig. 1. To

- the bottom or lower end of the T 6 is connectthe water in the tank and of course be coned the tank-pipe 13 by means of the elbow 14 or its equivalent. To the top or upper end of the tank-pipe 13 is attached the tank 15, which tank may be of any desired. size and is for the purpose of filling the radiator 1 and at the same time containing a suflicient amount of water to normally cover the steam-vent pipe '16, which vent-pipe leads into the bottom or lower end of the tank 15 from the opposite upper end of the radiator 1, to which the pipe 5 is attached, or, in other words, the waterpipe' 5 is attached to the lower portion of the radiator 1 and the vent-pipe is attached to the upper end and upon the opposite edge from that to which the water-pipe is attached. Inuse the radiator and tank are supplied with water and asuflicient amount of water to have the normal water-line above the outlet of the vent-pipe 16.

' In use the burner 8 when supplied with fuel will'heat the coil-pipe '7 and of course the water contained therein, and the water will circulate by reason of the heat in the usual manner, or, in other words, the heated water will move upward and the cold water downward and a continuous circulation be brought about. For the purpose of providing for the escape of steam the tank 15 is open at its top; but the vent-pipe is covered with water, so that any escape of steam will be mingled with densed, so that there is no visible exhaust of steam at any time.

It will be understood that by my peculiar arrangement I am enabled to provide a waterheater that can be moved from place to place and one that contains a heating device independent of any boiler or outside heating system, thereby providing a cheap water-heating system and one well adapted for use in dwell ing-houses and other places without the necessity of installing an expensive and complicated water-heating system. The burner 8 and its connections form no particular part of the present invention, so far as detailed construction is concerned, but should be so formed that it can be easily attached to the radiator proper and is movable with the radiator. The gas-pipe 17 may be formed of flexible material, thereby providing means for changing the position of the radiator or heater proper with reference to the gas-pipe 4. By providing the tank-pipe 13 and extending it down- Ward and connecting the same to the T 6 water will pass from the tank into the bottom or lower end of the radiator, and as the radiator I claim as new, and desire to secure by Letters Patent, is-

In a heater of the class described, a radiator, inlet and outlet waten-pipes connected thereto, a heating-pipe located intermediate the inlet and outlet pipes, and a burner adapted to heat the heating-pipe, a tank located above the burner and a feed-pipe for said tank extended below the burner and communicatingwith the lower portion of the radiator, and a vent-pipe leading from the upper portion of the radiator and communicating with the tank at a point below the normal Water-line of the tank, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two Witnesses.
